Katherine R Hulme, Jon van den Burg
INTRODUCTION: A cell salvage device is used in cardiac surgery with the aim of reducing allogeneic blood transfusion. Suction of blood from the operating field used for the device is often accompanied by diathermy smoke. There is limited published research to know if this blood is then contaminated with clinically significant levels of harmful chemicals from this smoke. Postoperative cardiac surgery patients are already physiologically vulnerable, making the optimization of salvaged blood worth considering...

OBJECTIVES: The first publication of Loeys-Dietz syndrome (LDS) described aortic rupture at young ages. Experience with new LDS types showed that the clinical course varies, and thresholds for prophylactic surgery are discussed. As this is an uncommon disease, experience needs to be shared. METHODS: Retrospective review of patients with LDS types 1-4 undergoing cardiovascular surgery during the years 1991-2016. RESULTS: Thirty-five patients (including 6 children with LDS2) underwent 57 operations...

Quadricuspid aortic valves (QAVs) are extremely rare. In this case study, we report a David-V valve-sparing aortic root replacement with reimplantation of a native QAV in a patient with aortic dilation, normal valve function, and a family history of aortic dissection. Microscopic pathological examination of the excised section of the aorta revealed scattered small foci of cystic medical degeneration throughout. A genetic predisposition for aortic dilation may be present in patients with QAV, even in the setting of a competent valve...

Surgery is indicated for symptomatic patients with papillary fibroelastomas (PFE) on the aortic valve. The valve is commonly spared during tumor excision. Rarely, aortic valve replacement (AVR) is needed. We present a case requiring AVR for an aortic valve PFE and review the literature to determine the risk factors for failure of aortic valve-sparing techniques in patients with PFE.

OBJECTIVES: The effect of performing aortic valve repair in combination with valve-sparing operation on the length of time for which patients are free from reoperation is unclear. The objective of this study was to determine if the performance of aortic valve repair during valve-sparing operation modified the freedom from reoperation time. METHODS: From January 2003 to July 2014, 78 patients with a mean age of 49±15 years underwent valve-sparing operation. Sixty-eight percent of these patients were male...

AIMS: The aim of this study was to evaluate the clinical and echocardiographic results and the predictors of outcomes in patients undergoing valve-sparing operation (VSO) at two aortic centers. In addition, we sought to evaluate the potential effect of recreation of the sinuses of Valsalva (SV) on the outcome of valve-sparing procedures. METHODS: During a 14-year period, 328 patients underwent aortic valve-sparing root replacement at two institutions. Clinical and echo evaluation was performed 6 months after surgery and every year thereafter or in case of clinical symptoms...

OBJECTIVE: In case of concomitant aortic regurgitation (AR) valve, sparing operation is considered the first choice in selected patients. The aim of this retrospective clinical and echocardiographic study was to evaluate the long-term survival results of conservative approach and the determinants of recurrent AR. METHODS: From 2000 to 2011, fifty patients (median: 63 years and interquartile range: 53-72) underwent an aortic valve-sparing procedure for acute aortic dissection, and discharged alive...

A 50-year-old man with no history of cardiovascular disease was referred to our hospital because of an abnormal electrocardiogram. Echocardiograms and computed tomograms revealed a 9-mm mass on the underside of an aortic valve leaflet. We chose surgical treatment, to prevent embolic events. The tumor's appearance and intraoperative frozen section were consistent with myxoma. We resected the tumor and its attachment, including the free margin of the aortic valve leaflet, and repaired the defect with use of a glutaraldehyde-treated autologous pericardial patch...

OBJECTIVES: Bicuspid aortic valve (BAV) is frequently associated with aortic insufficiency (AI) due to cusp disease and/or aortic root dilatation. Based on functional classification and morphology, a systematic surgical approach was used for aortic valve repair (AVr). METHODS: : From 2004 to 2014, 152 consecutive patients (mean age 55 ± 7 years) with BAV underwent AVr with or without concomitant aortic root surgery. Cusp pathology was treated with central plication in 60 (39...

BACKGROUND: Loeys-Dietz syndrome (LDS) is an aggressive aortopathy with a proclivity for aortic aneurysm rupture and dissection at smaller diameters than other connective tissue disorders. We reviewed our surgical experience of children with LDS to validate our guidelines for prophylactic aortic root replacement (ARR). METHODS: We reviewed all children (younger than 18 years) with a diagnosis of LDS who underwent ARR at our institution. The primary endpoint was mortality, and secondary endpoints included complications and the need for further interventions...

The strategy of root reconstruction for Stanford type A aortic dissection (AAD) includes resection of the intimal tear site, correction of concomitant aortic valve dysfunction and amendment of coronary lesion. Supracommissural tube graft replacement is a well-adopted and convenient procedure for most patients, although its application is limited when distinct sinus expansion and severe intimal damage is present. Composite valve conduit replacement (Bentall procedure) is suitable for patients with overt sinus damage...

BACKGROUND: Repair of complete atrioventricular canal (CAVC) with tetralogy of Fallot (TOF) is a challenging operation increasingly being performed as a complete, primary repair in infancy. Previous studies have focused on perioperative outcomes; however, midterm valve function, ventricular function, and residual obstruction have received little attention. METHODS: We retrospectively reviewed 20 patients who underwent CAVC/TOF repair (January 2005 to December 2014)...

OBJECTIVES: Severe cases of infective endocarditis (IE) of the aortic valve can cause aortic root destruction and affect the surrounding structures, including the aortic-mitral continuity, the anterior mitral valve leaflet and the roof of the left atrium. Reconstruction after resection of all infected tissue remains challenging. We describe our surgical approach and the mid-term results. METHODS: Between January 2004 and December 2015, 35 patients underwent surgery for extensive IE of the aortic valve with destruction of the aortic root, the aortic-mitral continuity and the mitral valve...

OBJECTIVES: Valve-sparing operations and root replacement with a biologic composite conduit are viable options in aortic root aneurysm. This study was conceived to compare the early and mid-term results of these 2 procedures. METHODS: From September 2002 to November 2015, 749 consecutive patients underwent either a valve-sparing operation or a root replacement with a biologic composite conduit at 2 institutions. Propensity score matching was used to compare similar cohorts of patients in the overall population and in the ≤ 55 and ≥ 65-year age groups...

Both aortic valve commissural detachment and commissural fenestration are rare causes of aortic regurgitation. In general, aortic valve replacement is the mainstay treatment for aortic regurgitation caused by commissural detachment or commissural fenestration. We herein describe valve-sparing aortic root re-implantation and aortic valve repair for aortic regurgitation and aortic root dilatation in an extremely rare case accompanied by both commissural detachment and commissural fibrous strand of fenestrated cusp...

Valve-sparing aortic root reconstruction is an up- and-coming approach for patients suffering from aortic valve insufficiencies which promises to significantly reduce complications. However, the success of the treatment strongly depends on the challenging task of choosing the correct size of the prosthesis, for which, up to now, surgeons solely have to rely on their experience. Here, we present a novel machine learning based approach, which might make it possible to predict the size of the prosthesis from pre-operatively acquired ultrasound images...

OBJECTIVE: We describe a simple method to assess the aortic valve using a videoscope inserted in the left ventricle (LV-VS) during valve-sparing root replacement. The aim of this study was to evaluate the feasibility of this technique by comparing it with the findings of postoperative transesophageal echocardiography (TEE). METHODS: Thirty-six patients (29 male, mean age 45.4 ± 20.1 years) undergoing aortic root reimplantation were assessed intraoperatively with LV-VS...
